n. the inclusion of parties (plaintiffs or defendants) or causes of action (legal claims) in a single lawsuit contrary to statute. Reasons for a court ruling that there is misjoinder include: a) the parties do not have the same rights to a judgment; b) they have conflicting interests; c) the situations in each claim (cause of action) are different or contradictory; or d) the defendants are not involved (even slightly) in the same transaction. In a criminal prosecution the most common cause for misjoinder is that the defendants were involved in different alleged crimes, or the charges are based on different transactions.
